Yes. Neuropsychological testing is one of the most thorough ways to evaluate ADHD in adults. The evaluation assesses attention, working memory, processing speed, and executive function across standardized measures, and also rules out other conditions that can mimic ADHD, such as anxiety, depression, or sleep disorders. For adults seeking an ADHD diagnosis or documentation for workplace or academic accommodations, a neuropsychological evaluation provides the objective, comprehensive evidence that is required.
